Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property saw petroleum bulk storage operations predating 1974, including a 6,000-gallon underground gasoline storage tank that was not discovered until 1998. The site later operated as a furniture warehouse and then as the Pavilion Mall beginning in 1982, with extensive petroleum contamination found beneath the former mall building. Cleanup under the Voluntary Cleanup Program included removal of over 27,000 tons of petroleum-contaminated soil, purging and removal of the orphan UST, groundwater pumping and disposal, and a multi-year groundwater monitoring program with wells installed in 1999 and 2000 that confirmed decreasing contaminant levels. The site received a No Further Action determination after capping with asphalt. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

Petroleum contamination at this property originated from bulk storage infrastructure — including a 6,000-gallon gasoline UST — installed and operated more than a decade before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The scale of documented remediation costs here is substantial: excavation and disposal of over 27,000 tons of contaminated soil, tank removal, groundwater recovery, and years of monitoring. Historical carriers who issued CGL policies covering operations at this site during the pre-1986 window may still be obligated to reimburse those cleanup expenditures.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

What We Look For

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
